System Unit: The main part of a computer that is held together by a plastic or metal enclosure. It holds the mother board, and any circutry attached to the mother board, cooling fans, disk drive, and a power supply. CPU: Central Processing Unit, the "Brain" of the computer, It controls everything that the computer does.
Silicon Chip: Microscopic pieces that make up the CPU. Hertz: the SI unit of frequency, equal to one cycle per second RAM: Random-Access Memory, Stores information that the computer (at that time) is holding. ROM: Read-Only Memory, Holds data information for the computer that does not change. Bit: A type of mesurement that works in the Binary Numerical System. Byte: In computer science a byte is a ubiquitous unit of storage measurement. It is also one of the basic integral data types in many programming languages. (1 byte = 1 character) Kilobyte: 1024 (210) bytes/ 1000 bytes Megabyte: 220 (1,048,576) bytes/ one million bytes Gigabyte: a measure of storage capacity equal to 1 billion (109) bytes Storage Devices: A hardware device, such as a hard disk or floppy disk, used to record and store data Medumm/Media: one of the means or channels of general communication, information, or entertainment in society Hard Drive: a hard drive is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Input Devices: A device, such as a keyboard, used to enter information into a computer Output Devices: A device, such as a printer, video display, or speaker, that presents data from a computer to a user Resolution: the degree of sharpness of a computer-generated image as measured by the number of dots per linear inch in a hard-copy printout or the number of pixels across and down on a display screen. Pixels: The basic unit of the composition of an image on a television screen, computer monitor, or similar display Peripheral Devices: any device attached to a computer in order to expand its functionality
